Mikuni Alicein

Mikuni Alicein is the older brother of Misono Alicein and eve of Doubt Doubt.

History
Mikuni was the first child of Mikado Alicein and seemed to have a good life for a long time. He was educaded by a house teacher (which is revealed to be Misonos mother) and Hattori. According to Hattori, Mikuni used to be a very talentated chess player and even won against Hattori and his father.

After Mikuni's mother killed Misono's mother out of jealousy she and his father took Misono into their house and Mikuni got a little brother. Mikuni started to hate his father for betraying his mother, but he also truly loved Misono.

One night his mother also attempted to kill Misono, because she was still consumed with jealousy - Mikuni did not want his beloved brother to be killed and killed his mother insead in order to save his brother's life.

After that incident, he and Doubt Doubt left the manor.

It's not known what he did in the meantime, but when he was on the street, he was found by the young C3 member Tsurugi Kamiya. Tsurugi took Mikuni in and Mikuni eventually became a member of C3 too. He shared his room with Tsurugi and was also in a C3 team with him. It is revealed in Chapter 45 that part of the reason why Mikuni hates Tsurugi seems to be because of the fact that Tsurugi has been killing humans, not just vampires. It is not revealed yet how long he had been with C3,he left the organisation to go his own way.

Storyline
He appears the first time, when Sleepy Ash is falling in rage in chapter eight. He succedes with his Servamp Doubt Doubt to calm Sleepy Ash back down with shooting him several times in his back.

Just before hand he had phoned Dodo to bring Misono into a hospital, because he was hurt in battle.

Mikuni only tells Mahiru his fist name, but does not say anything about being Misonos older brother. Mahiru doesn't know what to think about Mikuni, because he conciders him strange as he is talking to a doll called Abel. But Mikuni is the one who explaines to him, that if the eve doesen't know what he wants or fears the Servamp's power the Servamp falls into rage and devours his own eve.

He offers Mahiru to end the treaty with Sleeyp Ash for him, so he seems to know how it workes, but Mahiru refuses. Just before he leaves, he tells Mahiru, that he should have killed Sakuya to do him a favour.

The next time he meets Mahiru is when he and Doubt Doubt are in battle against one of Tsubakis Subclass. Therefore he uses his Lead "My fair Lady" in which his Doll Abel grows as heavy as the sins of his target. After the Subclass dies due to Doubt Doubts bite, Mahiru tells Mikuni that this kill was unnecessary, but Mikuni disagrees: they were in war after all - and Tsubaki alongside his Subclass were the enemies.

Mahiro does not complain any further but askes Mikuni to show him how to use his Lead instead. Mikuni thinks Mahiur is naive because he is too goodwilling but agrees to help him - now he reveals his full name and thanks him for becoming friends with his brother Misono.

Some time after the two of them are sitting in a restraurant but Mahiru still can't believe, that Mikuni should be Misono's brother, because the differ so much from each other. Then Mikuni starts to behave like Misono and complaines very noisy about the restraurant and uses bad language. Mahiru is truly embarrased  by this behavior and apologies in Mikuni's name.

After that he shows pictures of Misono's childhood and explaines that Servamps have served the Alicein houshold for many generations. He expresses he would like to work together with Mahiru and that Sleepy Ash is the strongest of all Servamps. He also explaines that he wants to collect information about Tsubaki to be abel to defeat him and stop his plans. After that Mikuni tells Mahiru about an oragnization led by humans who work to stabilize the coexistence of humans and vampires (later it is revealed that he talks about C3).

He promises Mahiru to train him.

Training with Mahiru and Co.
When they meet for training, Mahiru brought another eve with him: Testu Sendagaya. Mikuni agrees in training him too - but also makes clear, that he can train them only for one week. He tasks the two of them to blow Jejes bags from his head.

Mikuni explaines to them how the lead works (in Mikuni's eyes it is used to bind the vampire and controll the Servamp but in Old Childs point of  view it is used to control the eve instead).

When Tetsu nearly succeeds in bringing the bags down Mikuni jumps on his Servamp's shoulders and covers his face. Mikuni is suprised by Tetsus stregnth.

At the 2nd training Mahiru brings also Misono and Misono recognizes his brother instantly and a little fight against Snow Lily and Jeje occurs. It is because Misono doesn't really intent to kill his brother that Lily can't do anything against Jeje - besides both Servamps are aware that Jeje is a lot stronger than Lily.

Mikuni then decides to leave for now and tell Mahiru, that the society often gives him fitting information, and that he should let go of what he doesn't really need and take what he needs. For Mikuni there are two things that are required to be always in a good position: that are information and power. He tells Mahiru that when he was in his age - he had both information and power and thats why Misono still hates him - but he doesn't want to go into detail because he does not trust Mahiru enough to give him this information.

The next time Mikuni is seen with in C3 - talking to Shuhei Tsuyuki who is a former classmate of his. It is revealed that Mikuni has good connection to the boss of C3. Mikuni tries to convince Tsuyuki not to recrute Mahiru because it wasn't worth it.

Later on he feels that something terrible would happen at his old home. Because he doesn't want to go there himself he askes Tsuyuki to go for him because the reason he doesn't want to go there is because it is his old home. A bit later when the Dshinn were floating out of the region fo the house Jeje askes if Mikuni really doesn't want to go there - but he anseres in a hard voice if Jeje realy had the right to go into that house.

Tsurugi Kamiya
After leaving the Alicein mansion, it was revealed that Mikuni became a member of C3. During this time, he Tsurugi, and Jeje were a team there. They shared a room together and got along well. Tsurugi even describes their time together as "shining days of youth". When Mikuni returns to C3 at the time Mahiru is there, it is made evident that Mikuni and Tsurugi no longer get along. It is implied that Mikuni occasionally visits C3 when Tsurugi remarks that Mikuni is only rumored to go there when he is on business trips, thus making an effort to avoid Tsurugi. They both go out of their way to pick fights with one another regardless of the time or place. The fighting between them varies from verbal arguments that can be seen as playful or comical to actually trying to kill each other. Contrasting his actions, Tsurugi often expresses that he is happy to see Mikuni- whether he says that to spite him or if he genuinely means it is up to interpretation. When Tsurugi meets Misono for the first time he is reminded of Mikuni. He then begins to talk about the times they spent together. He states that Mikuni used to abuse him and order him around in exchange for money. Tsurugi says he did anything for Mikuni and that Mikuni was "wild at that age". He looks back at the experience as something positive.
